VThis invention relates to` improvements in ap-rr paratus for dyeing webs of material such as cloth or to improvements in a machine' commonly called a dye jig. e

The principal objects of the invention aredie rected to the provision of a novel dye jig which is characterized by its simplicity of form and its efficiency in operation. By means of the dyejig of the invention it is possible, without intricatemechanism, to obtain a constant speed `which is very important. There is produced a` dyed web, such as of fabric, which is without dark selvages and there is also a level dyeing from one end to the'other end of the batch. According tothis invention, the dye jig operates with a minimum of streaks, and it is adapted for various dyeing operations on all materials such as rayon and celanese. The dyeing operation is considerably quicker than with dye jigs heretofore `known without an injurious tension being applied to the web being dyed.

Various novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form of the invention, and it will be understood that various changes and modications may be made without` departing from the spirit and scope of the invention.

In the drawing Fig. 1 is a side elevational View, with some parts in section, of a dye jig embodying the novel features of the invention;

Fig. 2 is a partial transverse sectional` elevational view taken at one end of one of the winding mechanisms of the machine; and

Fig. 3 is a small scale diagrammatic view to explain the various driving connections of the machine shown in Fig. 1. t t

Referring now to the drawing in detail, the invention will be more fully described. The machine includes side frames such as 2 which may be tied together and held apart in spaced relation by transverse members such as 4. The said frames are adapted to rest on the floor F or upon a foundation if desired.

Between the frames 2 there is apan or vat 6 which inclines downwardly from its ends, as shown, to a depressed portion or sump 8 which may be supported on a transverse memberV l0. Through the depressed portion there may be one or more runs of pipe indicated by I2 into which steam or some other heating medium may be introduced. For purposes of heating the dye matef rial-contained in the sump and for some other purposes it is desired to have one or more pipes such as i4 in the sump portion which receive steam and is slit or perforated so as to deliver steam into the dyeing material.

valves in the Well-known manner. The web of material to be dyed is preferably handled in roll form and the web from a roll of materialV at one end of the machine is unwound and passed thru and wound up at the other end. For instance, the Web W from roll I6 passes between upper and lower rollers I8 and 20, over guides 22, `24, 26, 28, 30, 32, 34, between rolls 36 and 38 and is wound up in a roll 40. It may be assumed for purposes of description that the web is unrolled from the roll at the left of the machine, passed through the machine and rolled up again at the right of the machine.

If it is desired the web may pass through the machine in an opposite direction, or it may be passed through in one direction and returned through the machine in an opposite direction. The rolls I8, 20, 3B and 3B have their shafts journalled in boxes such as 42, 42', 46 and 46' which are slidable up and down in standards 50 and 52. There are two standards 5l) which are spaced apart at one end of the machine and there are other spaced apart standards 52 at the other end thereof.

The lower boxes 42' and 46' rest in the bottoms of vertical guideways of the standards as shown. The upper boxes may move up and down in the standards so that the upper rolls may rest on the lower ones or are urged thereagainst by means of springs 54. Plates 56 which are slidable in the standards are moved up and down by screws 58 which are in engagement with nuts 60 which are rotatable in caps 62 and they are rotated by worm gears 64 as shown. Transverse shafts 6B carry worms 68 in mesh with gears 64. By rotating the shafts, the plates 56 are moved up and down to tension the springs 54. In this way the springs cifer various degrees of resistance to upward movements of the boxes and the upper rolls carried thereby so that the pressure is variable. The rolls 2U and 38 are operatively connected so that they rotateV in timed relation relative to one another and to that end the shafts thereof carry sprockets T0 and 'l2 which are connected by a chain 14, (see Fig. 3). The roll 20 may be the driving element and to that end a motor 'I6 has a sprocket 18 and a chain 80 passes over' that sprocket 18 and another sprocket 82 assccated-with the roll 38.

` The amount of steam `1 admitted to the pipes may be varied by means of Friction disks Sii are keyed to the shafts 9G, and on their hubs there are rotatable, friction disks 93 (see Fig. 2). Movable disks I are slidable on the hubs of disks 9B but are non-rotatable thereon.` VFriction members |02 and |54 are provided between thev members Iil and 98 and between 93 and 96. Sleeve members SES are secured tov brackets 92 and have in screw threaded relation therewith A* nuts |08 in the form of handwheels and similar handwheels I l0. The devices i may be screwed along` the threaded member It@ to exert endwise pressure against the member itil and it may be locked in position by the member l lil. By means of the mechanism just described, it is possible to exert more or less end-wise pressure so as to produce various frictional effects. rEhe rolls and 38 have attached theretosprockets. l2 and ||l| engaging chains HE and H8 which pass around sprockets such as |20 and which are iixed to the intermediate member 98. i

As Z and are rotated the intermediate members as 98 are rotated thereby and the shafts 94 are driven through the irictional mechanism. It will be apparent that there may be more or less slip or frictional action between whatv mayV be called the drivers t3 and the shaftsfi so that the web may be fed through the machine in the desired manner.

Each shaft Q has associated ltherewith a drum |26 which is adapted to receive the end vof a winding arbor or shaft for the rolled up web and which is indicated by |28. A vband ESS in frictional engagement with the drum is secured to the bracket 92 and |32 and is adjustable at |34. The band resists rotation of the .shaft due to the irictional action between the band and the drum. The rolled up web to be dyed is. fed lthrough t'he machine as from left to right or. 'from right to left as may be'desired- Itmay be led.' therethroughl in one` direction for `a dyeing operation and reversed and led therethrough in an opposite direction all as may be' desired'and thev tension rmaybe regulated within wide limits so thatthe web is not strained to an injurious extent but yet is positively fed `so as to produce the desired results. X g i,

It will be noted that the tension of the Vweb may be -varied and that the frictional mechanism provides variationn within wide limitspfor driving the arbor for the roll which cooperates with the frictional drum mechanism so as to-prof vide wide range of flexibility all tothe e'nd'that the machine is capable of manyY and varioususes where it is desired to perform various operations on webs of all kinds. ,v l
